The working method of the ITLg. 1- ^r j daryoHtollton recorder will now be described in detail. The image data read by the devices CCD1 and CCD 2 are converted by the digitizing circuits 63 and 63 '

g binary digitized. The binary digitized data will be distinguished in color (red and black) by the color discriminator 64.

The color distinction is as shown in Table 1, carried out. The device CCD1 is sensitive to a white background (where there is no image information there) and insensitive to black and red originals, since it senses light with a short wavelength. on the other hand the device CCD2 is sensitive to the white background and a red original and insensitive with respect to a black original since it senses long wavelength light. As a result, if the template starts with the two devices CCD1 and CCD2 is scanned, the original is the white background. If the template doesn't is scanned with one of these sensors, the original is a black original. If the template with the establishment CCD2 is not scanned with the device CCD1, the original is a red original.

Executions CCD1 and CCD2 feel light. Only if the signals that output from the digitizing circuits 63 and 63 ', both of which are low in "L" level the AND gate AND 1 has a high level signal, i.e., a

r black signal B. Only when the signal coming from the Digitals output circuit 63 has a low level, and the signal output from the digitizing circuit 63 " is output, has a high level, the AND gate AND2 can send a signal with a high level, i.e. a red Sig-R produce.

The black or red signal is transmitted via the buffer circuit 65 is stored in the memory 66 which comprises a random memory (RAM) and others. The capacity of the memory 66 is

"L5 isn't particularly limited if just larger than that Bit number is that of the gap between the recording head 112 for recording in black and the recording head 114 corresponds to the recording unit 100 for recording in red, as will be described later.

The memory 66 may have a capacity similar to that of one Page memory is comparable.

Depending on the capacity of the selected memory 66, recording can be made when the original is read, or it can read information corresponding to one or more pages into a memory and then record it will. Only one CCD device also needs to be provided for reading. In this case the output is from the CCD device according to a number of threshold values

As a result, the data for the recording head 114 can be delayed for a certain time in which the recording sheet is shifted by the distance L. will. A memory is required for this in order to store data corresponding to this gap. The capacity this memory must be (the number of bits in the main scanning direction χ the number of lines of the gap pitch L).

The address, the timing, the read / write signal, etc. in order to read data from the memory 66 and to write into it, are supplied by the memory controller 6 7, which is controlled by the controller 83. The image data stored in the memory 66 is under control from the memory controller 67 to the buffer circuit 68. Black and red ones stored in the buffer circuit 68 Data are input to three color selection circuits 09 to 71. The three color selection circuits choose the black Signal B, the red signal R or a logical product R + B.

The signal selected by the three color selection circuits 69 to 71 is sent to the drive circuits 72 to 75 are applied to select the recording heads 76 to 79. Since the switching on / off of the control circuits 72 to 75 is controlled by the controller 83, the recording heads are turned if necessary selectively controlled. The controller 83 also controls the sheet feed systems 80-82, which the take-off rollers 102, 202 and 302, the registration rollers 104, 204 and 304, the feed rollers 105, 205 and 305 and 108, 208 and 308, etc.

In Fig. 17 is the circuit diagram of the control panel 54 and the three color selection circuits. In Fig. 17, with the control circuit 23, a selector switch SW1 for unit 1, a selection switch SW2 for the unit 2, a selection switch SW3 for the unit 3, a start key ST, a stop key SP, mode selection switch M11 to M18 of the unit 11, mode selector switch M21 to M23 of unit 2 and mode selector switch of unit 3 connected. The output of an OR gate OR 1 is with connected to a data selector DS1B. The outputs of OR gates 0R2 and OR 3 are with data selectors DS2 and DS3 tied together. The control circuit 23 is connected to the data selectors DS1B, DS1R, DS2 and DS3 via signal lines S1B, S1R, S2 and S3 connected.

The black signal B and the red signal R from the buffer circuit 68 are input to the color selection circuits 69 to 71, whereby the OR gates OR1 to OR3 become one get logical sum R + B. The signals B, R and R + B are entered into the data selectors DS1B, DS1R, DS2 and üS3. Select the appropriate data through the

2 bit lines S1B, S1R, S2, S3 from the control circuit 23 off the data signal lines. When unit 1 is selected by switch SW1, the mode switches become M11 to M18 effective. The mode switch M11 to M18 correspond to those shown in Table 2 Operating modes 1 to 8. Fig. 18 shows the data selected by the data selectors DS1B and DS1R

i ^ have been when the corresponding mode switches are switched on. When the unit 2 \ is selected by the switch SW2, the mode switches M21 to M23 become effective. The mode switches M21 to M23 correspond to the modes 1 to 3 shown in Table 3. FIG. 19 shows the data which have been selected by the data selector DS2 when the corresponding mode switches are switched on. A corresponding operation is performed when the unit is selected '.

Two or three of the switches SW1 to SW3 can be selected at the same time. Thus, by the combinations of unit 1 and mode 4, and units 2 and 3 and mode 1, a copy recorded in red (unit 1) and a copy recorded in black (unit 2) of the same data of a single original can be obtained at the same time . This enables color differentiation on sales coupons or labels, etc., and is very convenient and practical. If the unit ^and the. Mode 5 and units 2 and 3 and mode 2 are selected, a copy of the black data of an original with black and red data is obtained from units 2 and 3 as a further example. A copy of the red data from the same template can be obtained from unit 1 at the same time. This enables a color separation in it.

Thus, the recording device according to the invention has a number of recording sections which simultaneously a record on a number of recording materials perform a recording data generating Means for generating a number of parts or sections of record data, and a data selection means, to selectively the record information of the number of recording units. A number Copies can be made simultaneously from the recording units can be obtained. Furthermore, the same or different

• j ^ q second color recorded, which differed from the first Color differs. Consequently, if all of the recording units use the first recording device, a number of the same copies can be made in a short period of time. With the help of the second recording device a dichromic copy and a monochrome copy can be produced at the same time. This is special advantageous when issuing sales sections or labels, etc. In the embodiment described with reference to Fig. 13, there was only one recording unit among the three intended for a dichromic recording. However, two or three recording units can also be used, the second Recording device t recording heads for a dichromic recording).

The recording device of Fig. 24 has a first Drive circuit 85, a second drive circuit 86, a recording head 87 for black (which is the recording

- ^ q tion head 111 in Fig. 1), a recording head 88 for red (which corresponds to the recording head 211 in Fig. 1 ), a sheet feeding system 90 of the first recording unit (which corresponds to the recording unit 100 in Fig. 1, and a sheet feeding system 91 of the second recording unit (which corresponds to the recording unit 200 in Fig. 22). The controller 83 controls the overall circuit and the mechanical facilities. The control panel 84 has a dial for setting the number of records, the switch to determine the operating mode, such as recording in red, in black, or in black and red, as well as for recording one copy in black and another copy in red, the start button to initiate the recording process, etc. on.

Now the operation of the in 1 ' ¹ Iq. 7Λ darqer, LolH.on recording device described. The image data read by the units CCD1 and CCD2 are binary digitized by the digitizing circuits 63 and 63 ". The digitized data are subjected to color discrimination with respect to black or red at the color discriminator 64. The color discrimination is carried out as in FIG and has been described above in Table 1. The device CCD1 is sensitive to a white background (where there is no image data) and is insensitive to black and red originals, there

The device CCD2 i £; t sensitive to the white background and one red original and is insensitive to a black one Template because it feels light with a long wavelength. Thus, when the original by the two devices CCD1 and CCD2 is felt, the original is the white background. If the original is not sensed by one of these sensors the template is a 'black template, and if the Original is felt by the device CCD2 but not by the! Q device CCD1, the original is a red one Template. The black and red signals are stored in the memory 6 6 via the buffer circuit 65, which has a random memory (RAM).

To keep a record in red and black on different recording sheets thus, black and red data can be fed to the heads at the same time. To however to be recorded in black and red on the same recording sheet becomes, after recording by the black recording head 112 is finished, the same recording sheet to the recording unit 200 to be recorded by the recording head 212 in red.

The red data supplied to the recording head 212 must be delayed while on o.ino certain time which the recording sheet between the recording units is transported. As a result, the memory 66 must have a capacity to store data on one original page to save. The address, timing, and read / write signals to read the data from memory 66 or to write to it, are supplied from the memory controller 67, which is controlled by the controller 83.

The image data stored in the memory 66 is saved under

The black and red data of the buffer circuit 68 are transmitted to drive circuits 85 and 8 6, to record with the recording heads 87 and 88 perform. Switching the control circuits on / off 85 and 86 is controlled by the controller 83 so that the Recording heads are selected as required will.

The controller 83 also controls the sheet feeding systems 90 and 91, which are the take-off rollers 102 and 202, which are the registration rollers 104 and 204, which have feed rollers 105, 205 and 108 and 208 and so on. These rollers are powered by the energy passing through belts (not shown) and Couplings has been transmitted from a (also not shown) power source. Energy sources such as stepper motors, can be connected directly to the individual motors.

The controller 83 turns the clutches of these rollers on and off in series to feed the recording sheet, as described with reference to FIG. With regard to the recording heads, the sheet feeding systems 90 (corresponding to of recording unit 100) and 91 (corresponding to recording unit 200) are selected, to record with the selected recording unit.

After black data is recorded, the head 87 is turned off (step 585). to the recording sheet is then located at this point in time on the registration roller 205 of the recording unit U2. Consequently then becomes the sheet feeding system 91 of the recording unit U2 turned on except for the take-off roller 202. The sheet feeding system 90 of the recording unit U1 is switched off. The separator 89 is held in the position in which the Recording sheet is fed to the recording unit U2 (step 586). After a predetermined time from the shutdown of the sheet feeding system 91, the Head 88 turned on for recording in red (step 587). After recording red data, the head will 88 turned off (step 588). Consequently, in dichromic recording, when the black data is on the recording sheet recorded in the recording unit U1 the recording sheet is not ejected into the tray but for recording in red to the recording unit U2 is promoted and only then discharged. When the recording paper at the respective Operating modes is carried out in the storage areas 111 and 211, the sheet feeding system is turned off (step 589), whereby this recording process is then ended.
